Effect of nutrients on interactions between two decay fungi and Trichoderma harzianum Rifai on ponderosa pine sapwood wafers

Creator:: Canessa, Edwin
Abstract:: Small size wood assays were utilized to study the effect of added nutrients to the wood on the interactions of Trichoderma harzianum Rifai and two wood decay fungi, Trametes versicolor (white rot) and Gloeophyllum trabeum (brown rot). Weight losses related to time of exposure were monitored as a measure of...

Extraction of proteins from wood samples colonized by bioprotectants and/or stain fungi

Creator:: Cui, Li
Abstract:: Biological stain (blue stain) reduces wood value and prevents its use in many structural applications. Increasing environmental concerns have restricted the chemicals available for controlling this damage. As a result, biological control has received more interest. The application of these systems to wood has been limited due to their inability...

Fungal colonization of Douglas-fir sapwood

Creator:: Kang, Sung-Mo
Abstract:: The fungi that cause mold and stain of freshly sawn lumber result in millions of dollars in losses to the forest products industry. Stain and mold are typically prevented by either kiln drying or by application of a topical fungicide. While these treatments are effective, kiln drying is costly and...

The role of lytic enzymes in biocontrol of sapstain fungi

Creator:: Liu, Jiajian
Abstract:: The biocontrol potential of Trichoderma harzianum strains B-2A, B-8A, B-4B, B-15B, and B-41 and Serratia plymuthica was evaluated using agar plates and wood wafers of unseasoned ponderosa pine (Pinus ponderosa laws). All five isolates of Trichoderma harzianum and Serratia plymuthica could inhibit stain fungi growth in agar plates and exhibited...

Pressure measurement in wood as a method to understand impregnation processes : conventional and supercritical carbon dioxide

Creator:: Schneider, Philip F.
Abstract:: Two approaches to improving wood treatability include the modification of pressure schedules during conventional liquid treatments and the use of supercritical fluids (SCFs). In both of these techniques, pressure differences are important for transporting materials into wood. The level of pressure and its change during SCF treatments are also important...

Decomposition of Basamid in Douglas-fir heartwood

Creator:: Forsyth, Paul Griffin
Abstract:: Basamid^R (3,5-dimethy1-1,3,5,2H-tetrahydrothiadiazine- 2-thione) is a crystalline powder used as a soil sterilant. This fumigant acts in soil by decomposing to methylisothiocyanate (MITC), the primary active ingredient, as well as hydrogen sulfide, methylamine, and formaldehyde. In wood, Basamid decomposes too slowly to be efficacious against decay fungi unless amended with various...

Fungitoxicities of NaMDC decomposition products to decay fungi colonizing Doulgas-fir and ponderosa pine wood

Creator:: Canessa, Edwin
Abstract:: Metham sodium or NaMDC is one of the four major soil fumigants that are currently registered for controlling internal decay of wood products in use. Fumigants are used primarily in utility poles but are also applied to piling, timbers and other large wood members. NaMDC must decompose to fungitoxic compounds...

Controlling biodeterioration of western wood species with over- the-counter wood preservatives

Creator:: Newbill, Mark A.
Abstract:: Over-the-counter (OTC) wood preservatives can provide wood with both a moisture barrier and fungicidal protection against biodeterioration, yet there is little comparative data on the performance of these preservatives. In this study, the potential of various low-toxicity, OTC preservatives was evaluated on five western wood species, western red cedar (Thuja...
